Second vet visit today. Louis is up to 7.6 lbs, congestion is gone, hydration is much better.
He's not complained about being in the kennel except when I reach in to bring him out for treatment. Louis does not like to be handled. He is getting stronger and I've begun to consider the virtues of Kevlar sleeves! He has a lot of health concerns to be addressed but he seems content to hang out for the long haul. Maybe one day I'll be able to pet him.
